What do you think is really going on?

earlier this week, my 4 year relationship ended for reasons beyond me. I really wanted to work it out and continue it since his issues are fixable with therapy which I could’ve supported with him. He kept saying the same thing of needing space so he can understand himself better and what he wants from life since he started becoming unsure of that too. What made me confused was that he went to a drastic measure to end the relationship when nothing necessarily horrible happened, and it still doesn’t make sense to me on what was the benefit behind that for him besides that he wasn’t trying to string me along and let me be “free” when I still wanted to be with him. He stated that he was unsure on if he wanted to continue a relationship with me after therapy, didn’t really want to communicate with me while he was going through this process, and basically have nothing to do with me anymore. Again, very drastic over something I’m not at fault for.

coincidentally, his mom texted me the same day we broke up and I told her what happened. She was saddened by the news, and the following night she texted again to check in on me. I didn’t have a close bond with her since she had said rude stuff to me before. But, she disclosed to me that the whole “family” specifically her mom, her husband, and her daughter believe he’s doing this to mature/straighten up before committing to me/marriage. I didn’t say much about it besides “I hope,” and then she asked if I would spend time with her on Sundays for church since I planned on moving to his city for him in a couple of months for school. I said sure just to not be rude, and that was that. But, now I’m unsure if she made that claim after talking with her son about it or if they were assuming. It’s giving me false hope indirectly if it isn’t true about the relationship especially since he didn’t give off those impressions during the breakup. What do you think?

Whenever I talked with him a couple of times though about mailing an item out for me that I wanted back, he kept saying how he just needed time/space. That was also kind of implying that after he gets enough time/space to process things, he’d want to continue again to me but I’m not sure if I interrupted it the wrong way
